What does plumber mean?
A plumber is a person who installs, repairs, and maintains pipes and related plumbing systems. The term is especially common for a trade professional called to fix leaks, replace damaged sections, and work on water, waste, and heating pipework. In ordinary speech, “plumber” usually means a practical, skilled worker rather than a general handyman. It can also carry an informal connotation of someone who solves household problems quickly or who is called in during an emergency. Less commonly, especially in American political language, “plumber” means a person secretly engaged in political intelligence or covert operations; this sense is strongly associated with the Watergate era. The word is therefore both a straightforward label for a modern trade and a historical political metaphor. Learning it is useful because the occupational meaning is common in everyday English, while the specialized political sense explains a number of older headlines and historical accounts.

Where does plumber come from?
The word was borrowed into Middle English from Anglo-French and Old French forms meaning a worker in lead. It ultimately derives from Latin plumbarius, “lead worker” or “one who works in lead,” which was formed from plumbum, the Latin word for lead. The connection reflects the historical use of lead pipes in water systems; related English words include plumb and plumbing.
